Background

Organic Light Emitting Diode (OLED) Display devices are one of the hot spots in the research field of flat panel displays, and compared with Liquid Crystal displays, OLED Display devices have the advantages of low energy consumption, low production cost, self-luminescence, wide viewing angle, fast response speed, and the like.

The structure of the OLED display device mainly comprises: the liquid crystal display device includes a substrate base plate, and pixels arranged in a matrix on the substrate base plate. In general, each pixel is formed by an organic material through a high-precision metal mask by using an evaporation film forming technique, and an organic electroluminescent structure is formed at a corresponding pixel position on an array substrate. However, in the current OLED display device, the distance between pixels in the pixel arrangement structure is large, so that the pixel opening area is small under the condition of the same resolution, and thus the driving current needs to be increased to meet the display brightness requirement. And the OLED works under a large driving current, so that the aging speed of the device is increased easily, and the service life of the OLED display device is shortened.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed description will be omitted. Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

Although relative terms, such as "upper" and "lower," may be used in this specification to describe one element of an icon relative to another, these terms are used in this specification for convenience only, e.g., in accordance with the orientation of the examples described in the figures. It will be appreciated that if the device of the icon were turned upside down, the element described as "upper" would become the element "lower". When a structure is "on" another structure, it may mean that the structure is integrally formed with the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure via another structure.

The terms "a," "an," "the," and "said" and variations thereof herein are used to indicate the presence of one or more elements/components/etc.; the terms "comprising" and "having" are intended to be inclusive and mean that there may be additional elements/components/etc. other than the listed elements/components/etc.; the terms "first," "second," and "third," etc. are used merely as labels, and are not limiting on the number of their objects.

The most common pixel arrangement modes include Real RGB (traditional subpixel arrangement mode), Pentile (pixel arrangement), Delta (Delta) and other pixel arrangement modes, and each pixel arrangement mode has both advantages and disadvantages. The Real RGB display effect is best, but the resolution of the product is low due to the limitation of various process factors due to the large number of pixels. The Pentile pixel arrangement has the advantage that the resolution can be made to be higher level under the condition of the same pixel interlayer gap, and the disadvantage is that the pixel borrowing can increase the complexity of a pixel algorithm. The space utilization rate of the Delta pixel arrangement mode is high, and the display effect has obvious saw-tooth feeling.

In the related-art pixel arrangement structure, the red sub-pixel is located at a center position of the first virtual quadrangle and at four vertex positions of the first virtual quadrangle; the blue sub-pixel is positioned at the midpoint position of the side of the first virtual quadrangle; the green sub-pixel is positioned in a second virtual quadrangle, the second virtual quadrangle is formed by sequentially connecting two blue sub-pixels positioned at the middle points of two adjacent sides of the first virtual quadrangle and red sub-pixels which are adjacent to the two blue sub-pixels and respectively positioned at the center position of the first virtual quadrangle and the vertex angle position of the first virtual quadrangle, and the four second virtual quadrangles form the first virtual quadrangle. And the long side direction of the blue pixel is along the positive and negative 45-degree direction, so that the sagging amount is easily generated in the actual stretching, and the display effect is influenced.

Moreover, in the organic electroluminescent display device, due to the great difference in the structural performance of the red, green and blue sub-pixels, the luminance of the blue and green devices is attenuated more rapidly. Therefore, it is very advantageous to increase the aperture ratio of the blue pixel to increase the display device.

Example embodiments of the present disclosure provide a pixel arrangement, such as the structural schematic diagrams of the pixel arrangement of the present disclosure shown in fig. 1-6, which may include a first sub-pixel 1, a second sub-pixel 2, and a third sub-pixel 3; in the first direction, the first sub-pixels 1 and the second sub-pixels 2 are alternately arranged to form a first row, and the third sub-pixels 3 and the second sub-pixels 2 are alternately arranged to form a second row; in a second direction, the first row and the second row are alternately arranged, the first sub-pixel 1 and the second sub-pixel 2 are alternately arranged to form a first column, the third sub-pixel 3 and the second sub-pixel 2 are alternately arranged to form a second column, and the first direction is vertical to the second direction; two adjacent first sub-pixels 1 are perpendicular to each other or two adjacent third sub-pixels 3 are perpendicular to each other, or two adjacent first sub-pixels 1 are perpendicular to each other and two adjacent third sub-pixels 3 are perpendicular to each other; the second sub-pixel 2 is arranged in a strip shape, and the length direction of the second sub-pixel 2 is parallel to the edge of the adjacent third sub-pixel 3.

According to the pixel arrangement structure, when the display is carried out, any one first sub-pixel, the second sub-pixel 2 adjacent to the first sub-pixel and the third sub-pixel 3 adjacent to the first sub-pixel can form a light-emitting pixel point, and therefore the display effect of high resolution is achieved between the sub-pixels through the low-resolution physical resolution by means of the color principle. Compared with the existing pixel arrangement structure, the pixel arrangement mode can enable the first sub-pixel 1, the second sub-pixel 2 and the third sub-pixel 3 to be tightly arranged under the same process condition, and reduce the distance between adjacent pixels as much as possible, so that the pixel opening area is increased under the condition of the same resolution, the drive current of a display device is reduced, and the service life of the display device is prolonged. The length direction of the second sub-pixel 2 is parallel to the edge of the adjacent third sub-pixel 3, the second sub-pixel 2 is expanded towards the long axis direction, and is reduced in the short axis direction, so that under the condition that the areas of the second sub-pixels 2 are the same, the space for accommodating the third sub-pixel 3 is increased, the third sub-pixel 3 with a larger area is conveniently arranged, and the display life of the third sub-pixel 3 is prolonged.

It should be noted that, in the above-mentioned pixel arrangement structure provided in the exemplary embodiment of the present disclosure, the mentioned vertical and parallel are not completely vertical or parallel, but have a certain error, the error range is ± 5 °, that is, the two are perpendicular to each other means that the included angle between the two is greater than or equal to 85 ° and less than or equal to 95 °, that is, the two are parallel to each other means that the included angle between the two is greater than or equal to-5 ° and less than or equal to +5 °, the positive and negative of the angle refer to the rotation direction, the counterclockwise is positive, and the clockwise is negative.

It should be noted that, in the above-mentioned pixel arrangement structure provided in the exemplary embodiment of the present invention, the pixels are alternately arranged to form a row or a column, which refers to the position range of the pixels, as long as it is ensured that the sub-pixels located in the same row are located in the first virtual rectangle 41 or the second virtual rectangle 42 extending along the first direction, and the sub-pixels located in the same column are located in the third virtual rectangle 43 or the fourth virtual rectangle 44 extending along the second direction. In practical implementation, the centers of the pixels in the same row may be located on the same straight line, and of course, the centers of the pixels may not be located on the same straight line, that is, the centers of the pixels are offset, which is not limited herein. The center of the pixel may be a geometric center of the pixel pattern, or may be a center of a light emission color of the pixel, which is not limited herein.

It should be noted that the pitch between the sub-pixels mentioned in the display arrangement provided in the exemplary embodiment of the present invention refers to the shortest distance between the edges of the sub-pixels that are close to each other.

Alternatively, in the pixel arrangement structure provided in the exemplary embodiment of the present invention, the first sub-pixel 1 may be a red sub-pixel, the second sub-pixel 2 may be a green sub-pixel, and the third sub-pixel 3 may be a blue sub-pixel; alternatively, the first sub-pixel 1 is a green sub-pixel, the second sub-pixel 2 is a red sub-pixel, and the third sub-pixel 3 is a blue sub-pixel, which is not limited herein.

The following description will be given taking an example in which the first sub-pixel 1 is a red sub-pixel, the second sub-pixel 2 is a green sub-pixel, and the third sub-pixel 3 is a blue sub-pixel.

The lifetimes of the different color sub-pixels are generally different, so the area of the sub-pixel can be set according to the lifetime of the sub-pixel, and the area of the sub-pixel with the lowest lifetime is generally set to be the largest.

Since the lifetime of the blue sub-pixel is the lowest in the current organic light emitting material, alternatively, in the pixel arrangement structure provided in the exemplary embodiment of the present invention, the area of the blue sub-pixel is larger than that of the green sub-pixel, and the area of the blue sub-pixel is larger than that of the red sub-pixel.
